Microsoft has released the optional preview update KB5124006 for Windows 11 version 26H1, which raises the OS build to 28000.3086. The update adds taskbar positioning, a smaller taskbar, Start menu size options, and new Windows Search privacy controls. For administrators, the more relevant changes are the rollout of Administrator protection, general availability of Autopilot device association, Microsoft Execution Containers (MXC) process isolation, and standalone ML-KEM for TLS. The update also removes WMIC from 26H1 and lists two known issues that affect domain-joined PCs and USB audio devices.
